Abstract
This research investigated the mechanical performance of slurry infiltrated high performance fiber reinforced cementitious composite (SI-HPFRCC) with high volume blast furnace slag powder. Hooked-end steel fibers (volume fraction of 6.4%) were used for the fabrication of SI-HPFRCC. A series of mechanical performance test was conducted including strength and toughness of SI-HPFRCC in compressive and flexural mode at four different ages. Compressive and flexural strength tests of the slurry matrix at the same ages were also conducted in order to evaluate fiber reinforcing effect on the mechanical performance. The flexural response of SI-HPFRCC shows an increasing brittleness with age. The compressive response also shows an increasing brittleness with age but the degree of brittleness is much lower than the flexural case. In terms of strength, SI-HPFRCC shows about 140~190% of compressive strength improvement and 440~500% flexural strength improvement comparing to the slurry matrix.
